私は仕事のためのプロジェクトを進めており、少しのロードブロッキングを実行しています。このプロジェクトでは、実際にユーザーがXMLファイルを生成できるようにします。ユーザは、最初に多数のGUIを提示される。これらのGUIは、第1のGUI上で選択されたものに依存する。ユーザーがGUIを使用して処理を進めると、そのデータはJTableを埋めるために使用され、XMLファイルに入れられると確認されます。メソッドエラー内のアクションリスナーでJFrameを閉じる
私はJFramesで問題にぶつかりました。ユーザーがGUI画面の情報を入力して「確認」ボタンを押すと、そのJFrameが消えて、次に表示されます。次に問題が出るのは問題ありませんが、クラスの設計上、JFrame.dispose（）メソッドを適切に使用する方法を理解できません。私は下の私のクラスを投稿します：
テスタークラス
package mainClasses;
import gui.AllGUI;
public class Tester
{
public static void main(String args[]){
AllGUI aGUI = new AllGUI();
aGUI.createAllGUI();

}
}
});
confirmPanel.add(confirmButton);
mainPanel.add(formPanel,BorderLayout.NORTH);
mainPanel.add(confirmPanel,BorderLayout.CENTER);
return mainPanel;
}
private void addComponent(Container container, Component component, int gridx, int gridy, int gridwidth

,anchor, fill, insets, 0,0);
container.add(component,gbc);
}
}
第二のGUI画面具体的
package gui;
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.Container;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
public class TCRSpecificGUI
{
private static final Insets normalInsets = new Insets(10,10,0,10);
public void createTCRSpecificGUI(){
JFrame frame = new JFrame("TCR-Specific Tags");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(createMainPanel());
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
private JPanel createMainPanel(){
JPanel mainPanel = new JPanel(new BorderLayout());
JPanel formPanel = new JPanel(new GridBagLayout());
int gridy=0;
JLabel proprietaryPartyTypeTitle = new JLabel("Proprietary Party Type:");
addComponent(formPanel,proprietaryPartyTypeTitle,0,gridy,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);
JTextField proprietaryPartyTypeText = new JTextField("",10);
addComponent(formPanel, proprietaryPartyTypeText,1,gridy,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);
JLabel proprietaryPartyIdTitle = new JLabel("Proprietary Party ID:");
addComponent(formPanel, proprietaryPartyIdTitle,2,gridy,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);
JTextField proprietaryPartyIdText = new JTextField("",10);
addComponent(formPanel, proprietaryPartyIdText,3,gridy++,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);
JLabel transactionDateTimeTitle = new JLabel("Transaction Date/Time:");
addComponent(formPanel, transactionDateTimeTitle,0,gridy,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);
JTextField transactionDateTimeText = new JTextField("",10);
addComponent(formPanel, transactionDateTimeText,1,gridy,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);
JLabel rMessageFileNameTitle = new JLabel("R-Message File Name:");
addComponent(formPanel,rMessageFileNameTitle,2,gridy,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);
JTextField rMessageFileNameText = new JTextField("", 10);
addComponent(formPanel, rMessageFileNameText,3,gridy++,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);
JLabel supplementaryXPathTitle = new JLabel("Supplementary X-Path:");
addComponent(formPanel, supplementaryXPathTitle,0,gridy,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);

addComponent(formPanel, supplementaryXPathText,1,gridy,1,1,normalInsets,GridBagConstraints.LINE_START
,GridBagConstraints.HORIZONTAL);
JPanel confirmPanel = new JPanel();
JButton confirmButton = new JButton("Confirm");
confirmButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
}
});
confirmPanel.add(confirmButton);
mainPanel.add(formPanel,BorderLayout.NORTH);
mainPanel.add(confirmPanel,BorderLayout.CENTER);
return mainPanel;
}
private void addComponent(Container container, Component component, int gridx, int gridy, int gridwidth
,int gridheight, Insets insets, int anchor, int fill){
GridBagConstraints gbc = new GridBagConstraints(gridx, gridy, gridwidth, gridheight, 0.0D, 0.0D
,anchor,fill,insets,0,0);
container.add(component,gbc);
}
}
最初のGUI上のJComboBoxの選択でしょう次に表示されるGUIを決定します。
confirmButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
if(fileTypesComboBox.getSelectedIndex()==0){
type="OTC";
TCRSpecificGUI tcrGUI = new TCRSpecificGUI();
tcrGUI.createTCRSpecificGUI();
}else if(fileTypesComboBox.getSelectedIndex()==1){
type="HOME";
}else if(fileTypesComboBox.getSelectedIndex()==2){
type="CLEARED";
}
}
});
ここでは、ユーザーがJComboBoxで最初のオプションを選択した場合のロジックしかありません。これは正しく動作し、新しいGUIが開きますが、最初のJFrameの上に開くだけです。それはのためのEclipseでエラーとしてフラグが立てられただし
if(fileTypesComboBox.getSelectedIndex()==0){
type="OTC";
JFrame.dispose();
TCRSpecificGUI tcrGUI = new TCRSpecificGUI();
tcrGUI.createTCRSpecificGUI();
：
Cannot make a static reference to the non-static method dispose() from the type Window
が、私はこのエラーが発生する理由を理解し、どのような私はこのようなアクションリスナー内JFrame.dispose（）を使用して試してみました問題は解決する方法がわかりません。私は数多くのアプローチを試みましたが、何も動作していないようです。最初のJFrameを閉じるときに、他のJFrameを閉じるときには、本当に助けてください。
：あなたのようなコードのものを使用することができ、あなたのボタンの
ActionListenerでそう！あなたの助けをありがとう！ – jesric1029
